System config.:

T7500 2.2ghz
1GB RAM

I tried it using ATItool and riva tuner

It's generally not recommended to overclock a graphics card, due to the laptop's limited frame and the heat buildup within the already hot chassis.

You should be able to overclock though, using Rivatuner and the proper drivers...of course, make sure you watch those temps and consider getting a laptop cooler and/or cleaning out the air vents and making sure airflow is properly maintained.

I tried it using Rivatuner and atitool but I couldn't overclock it. In atitool when I try overclocking it reverts to default clocks soon after changing the clocks. Since it is a new laptop the vents should be clear. I'll keep a watch on the temperatures. Can u tell me how to overclock it using rivatuner.

i rememeber i had that problem on my x1400 mobile. had to use a certain software to make it work. some cards might be locked from overclocking too.

What a terrible idea, it won't be worth the 2 fps you gain. You'll just fry the laptop and your warranty.

on a laptop it might be better to DOWNCLOCK your video card... loose 2 fps but drastically reduce heat and power...

Gaming can only be done a desktop, laptops are simply not powerful enough.

Underclocking won't save THAT much power

Undervolting will, and can usually be done at stock speeds with Core 2s, you just have to do it manually on the motherboard.

Yes but underclocking can be done with rivatuner... undervolting means messing with the hardware (there are no bios settings for that on a lappy)
